Be it known that I, DANIEL W. COLBY, a

citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Im-' provements in Machines for Setting Eyelets or Similar Fasteners, of which the following description, in connection with the accompanying drawings, is a specification, like which mechanism shall be operated from.

the main actuating lever of the machine.

To this end an important feature of the invention consists in the combination with the actuating lever for the setting, die, of a bodily movable cam connected with p the raceway and so shaped thatit'will impart an irregular movement to the raceway beginning after the initial movement of the setting die and, if desired, terminating before the end of the lever movement. this way the actuating lever may have a stroke of suflicient extent to impart a power'- ful pressure to the setting dies while the motion of the raceway need not be more than sufiicient'to carry its delivery end out of alinement with the dies. 40 The,invention is herein disclosed as embodied in a machine for setting D-shaped eyelets and to thiselid certain parts ofthe machine are peculiarly shaped. For example, the setting dies are made substantially D-shaped in cross section and are disposed with their flat sides' toward the front of the machine. The raceway, which extends from front to back, is so shaped as to deliver the D-shapedeyelets in corresponding It will be apparent, however,"that the invention is not limited in its broad application V r V sroitamns's'ncnusnrrs;'Assienro ro uisir'rn'n snon" MACHINERY comrnnmonrArEnson, NEW JERsEYfA ooRPoItA'TI'oN -oF Specification ofLet ters Patent.

Fig. a is a fragmentary sectional view on the line 66 of Fig. 3. 7 v

As herein shown the machine comprises a flatbase. plate 10 from which extends a vertical frame 12 and an ear 22 located on one side of the frame and spaced a short dis tance from it. The frame 12 is bifurcated and is provided in its upper arm with a socket for the upper setting die14. In the lower arm of the frame12 is provided a vertical bearing forthe plunger 16 which car-'- r1es at'its upper end'the lower setting die 18.

The lower setting die 18- is provided with The plunger 16 is actuated by means of the lever 24-which is journaled on a pin extending transversely between :the ear-'22 and $5 the frame 12. The lever 24=is forked at its forward end to'receive a transverse pin 26 5 .mounted in a slot in the lower'end of the plunger 16 and is provided, with bosses on each side of its axis which contact with a djustable stops on the base plate '10 and determine theliniits of the movement of the lever.' g

The raceway 36 issupported pivotally upon the upper ends of the lever 30'and link 32 and is movable fromfan initial position, in which the endinost eyelet in the raceway is located in alinement with the, spindle 20 of the lower setting die, as shown inFig. 2,-

to an inoperativeposition to the rear of the setting dies. v

The eyelet hopper is" mounted upon the rear end of the raceway and carried back and forth by the raceway in it'soscillations. The hopper herein disclosed is provided wih 10.5 a otatable casing 40 having a driving shaft Mimi-8,1916. 'Application iiled October 12,19 11. Ser'ia1 1io.654,241. j, 1

and roller connection. .As herein shown 't he.

lower end of the lever 30 is provided with a plate 34 in which is cut an interior cam surface. The lever 24 is ofiset outwardly at the rear of its pivot and passes outside the end of the raceway lever 30, being provided with a rolleron its-inner side mountedon a stud 28 and arranged to'project into thecamrear side of lever 24 in such a held againstend of the spindle 20 is raised movement of the raceway occurs.

in the plate 34. 'The shape of' the cafn is such that duringlthe first part of the working stroke of the lever 24 lostmotion occurs between the roller and the cam so that the suiiiciently before any After the eyelet has been thus engaged the roller encounters a projection in the cam surface and the'raceway is moved into its inoperative position. After the raceway has been so moved to impale the endmost eyelet further lost motion takes place between the roller and the cam during which the clenching inovem'ent of the lower setting die takes place. The position of the cam and roller at this time is indicated in dotted lines in Fig. 1... The lever 24 is actuated by a treadle' rod 25 and at'the completion of the setting operation a spring 27' connected with the treadle rod acts to elevate the rearend of .the lever 24 and retract the lower setting die. During the first part of. the reverse movement of the lever 24 the roller traverses the the cam without moving the raceway and during thisperiod the lower setting die is raceway. hen the lower setting dle has nearly reached its lower position the roller encounters the upper surface of the cax n and the raceway is moved forwardly to its in tial sition. It will be seen that the cam in the plate 34 coiiperates with the roller on the I way as to impart an 1rregula: movement to the raceway which terminates before the end of the working stroke of the lever while-the setting die is'un formly mov'ed by the lever. The raceway s movement while the roller is .not acting on the cam 34 by a frictionplug 'on the link 32, which engages a planeraised surface 33 on the frame.

As has been stated al ove, the illustrated machine is adapted for setting shaped eyelets. To this end the setting dies 14 and 18 and also the. center spindle 20 are made lD-shaped in cross section, as shown 1n Fig. 2. The straight sides of the setting dies are versely lowered below the path of the disposed toward the front of the machine so that the D-shaped eyelets shall be set with their curved sides toward" the edge of the work. In order to deliver the eyelets in the proper position to the setting dies the delivery end of the raceway is curved transing in its side through which the endmost eyelet is drawn .by the center spindle 20 when the raceway is moved orearwardly. The endmost eyelet is yieldingly retained in the raceway by a leaf spring 38 which extends over the end of the barrel of the eyelet and has a hooked portion arranged to engage the outer flat surface of the barrel.

/ Referring now to-the eyelet assorting device, as shown in Figs. 3 to 6, the circular base plate 42 is provided with a depressed track or-channel 50 havin on its inner edge a vertical shoulder. A cy indrical casing 40 is arranged to turnwith its lower edge on I the track 50 and is actuated from the central across the machine and has an openshaft 44 to which it is connected by radially extending arms. In the lower edge of the caslng 40 are formed. a plurality of open ended U-shaped recesses 48 the walls of which are tapered inwardly. from the inner surface of the casing. These recesses are each shaped to receive a. -shaped eyelet.

resting on its'flat side and receive the eyelets from the mass contained promiscuously in the hopper. .The upper end of the raceway 36 merges into the track 50 through an intermediate piece 54 which has cutin it a track so shaped as to tilt each eyelet passing over. it endwise so that it shall, rest on its flange; To this end the portion of the track on which the barrel of the eyelet rests is given a gradually increasing pitch as it approaches the upper end of the raceway and .the front wall of the track is correspondingly flattened as will be apparent from the sectional views shown in Figs. 5 and 6. On account of the inclination of the raceway and hopper the eyelets would drop out of the of the hopper if not'retained by the shoulder of the track 50. In order to prevent eyelets of the mass from reaching the raceway through the opening cutin the base plate for the iece'54 an angularguard plate 52 is provi ed. atthis point as shown in Figs. 3,5and6. f

f The eyeletassorting mechanism above described is not claimed 'hereinbutjforms the subject-matter of a-- divisional application Serial No. 39,207, filed July 10 1915.

It is believed that the opei'ation of the machine will be clearfrom the foregoing description but it may be briefly stated as follows: Eyelets' are poured promiscuously into" the hopper and such as happen to assurne proper positions enter the recesses 48 at the lower side of the. casing 40 and are carried to the upper end of the raceway by 1'30 the rotation of the casing, being turned endwise so as to rest on their flanges as they pass over the track in the section 54. The

previously punched work isthreaded over the upper setting die and the treadle rod depressed whereupon the center spindle engages an eyelet in the raceway, the raceway is retracted and the eyelet is carried upwardly, inserted in the work and clenched 1.
